DFX Series - Refrigerated Compressed Air Dryers 3,000 – 12,000 SCFM
The Deltech DFX Series refrigerated dryers represent a significant advancement in air compression technology, focusing on energy efficiency and operational cost-effectiveness. Utilizing the latest in heat transfer advancements, these dryers are designed to dynamically adjust energy usage based on the fluctuating demands of compressed air systems. This not only ensures a consistent supply of dry, clean air but also aligns with modern sustainability practices by reducing electricity consumption and operational costs.

Energy Saving Sustainability
The DFX Series lowers air system power costs and improves productivity by matching power consumption to compressed air demand. In a typical manufacturing facility, up to 30% of the electricity consumed is for generating and treating compressed air. To reduce the total cost of operation and qualify for utility company incentive programs, proper air treatment equipment selection and application is required.
Load Matching Performance
Compressed air load profiles in most manufacturing facilities fluctuate. The DFX Series provides cost-effective energy savings by matching electrical power consumed in direct proportion to air demand. Linear load matching is achieved from 0% up to 100% demand. Non-cycling dryers operate with the refrigeration compressor running continuously, regardless of inlet load conditions. Minimal energy savings are realized from 100% down to 0% inlet air load.
The DFX Series dryers feature a unique design that incorporates a 3-in-1 heat exchanger (pending patent).
- The DFX Series utilizes a phase change material (PCM) heat transfer medium between the refrigeration and compressed air circuits that serves as a reservoir for thermal storage.
- The thermal reservoir is comprised of a patent pending heat exchanger filled with a phase change material that efficiently transfers heat energy through a “change of state”. The PCM changes from liquid to solid back to liquid in a continuous cycle.
- The refrigeration circuit operates to cool down the PCM until it forms into a solid at which time the refrigeration system cycles off.
- As the compressed air enters the PCM to air section of the heat exchanger, the PCM media absorbs heat from the airstream and begins to thaw the PCM media at a constant temperature.
- When most of the PCM media has turned to liquid the refrigeration system cycles on to again cool down the PCM media turning it back into a solid.
- This cycle repeats as required to meet the corresponding compressed air load on the DFX Series dryer.
- This innovative approach to heat exchange in the DFX Series dryers demonstrates a significant advancement in temperature regulation technology.
